The process

The workpiece in the form of a tube is placed inside the die [1] of the required shape. An explosive charge, in this case in the form of a cartridge [2], is mounted so that the pressure wave is led up to the interior of the tube. Upon detonation an intense blast deforms workpiece [3] so that it assumes the shape of the die.
